As rakesh roshan said the source of the info you gave is not bona fide. The person makes a claim without scriptural proof. So let's take of look at what scriptures say about Lord Balarama:

vasudeva-kalanantah
sahasra-vadanah svarat
agrato bhavita devo
hareh priya-cikirsaya

“The foremost manifestation of Krsna is Sankarsana, who is known as Ananta.
He is the origin of all incarnations within this material world. Previous to
the appearance of Lord Krsna, this original Sankarsana will appear as
Baladeva, just to please the Supreme Lord Krsna in His transcendental
pastimes.” (SB 10.1.24)

TEXT 8

devakya jathare garbham
sesakhyam dhama mamakam
tat sannikrsya rohinya
udare sannivesaya

TRANSLATION

Within the womb of Devaki is My partial plenary expansion known as
Sankarsana or Sesa. Without difficulty, transfer Him into the womb of
Rohini.

garga uvaca
ayam hi rohini-putro
ramayan suhrdo gunaih
akhyasyate rama iti
baladhikyad balam viduh
yadunam aprthag-bhavat
sankarsanam usanty api

“Gargamuni said: This child, the son of Rohini, will give all happiness to
His relatives and friends by His transcendental qualities. Therefore He will
be known as Rama. And because He will manifest extraordinary bodily
strength, He will also be known as Bala. Moreover, because He unites two
families–Vasudeva’s family and the family of Nanda Maharaja–He will be
known as Sankarsana.”(SB 10.8.12)

Srila Praabhupada's Purport to Bhagavad Gita 10.37

"Kṛṣṇa is the original Supreme Personality of Godhead, and Baladeva is Kṛṣṇa’s immediate expansion. Both Lord Kṛṣṇa and Baladeva appeared as sons of Vasudeva, so both of Them may be called Vāsudeva. From another point of view, because Kṛṣṇa never leaves Vṛndāvana, all the forms of Kṛṣṇa that appear elsewhere are His expansions. Vāsudeva is Kṛṣṇa’s immediate expansion, so Vāsudeva is not different from Kṛṣṇa. It is to be understood that the Vāsudeva referred to in this verse of Bhagavad-gītā is Baladeva, or Balarāma, because He is the original source of all incarnations and thus He is the sole source of Vāsudeva. The immediate expansions of the Lord are called svāṁśa (personal expansions), and there are also expansions called vibhinnāṁśa (separated expansions)."

Even Balarama considers Himself to be a servant of Lord Krsna. Balarama is
the first expansion of Krsna and is the original spiritual master, and He
too has the sentiment that He is a servant of Krsna. In fact, every
conscious being is imbued with the sentiment of being a servant of Krsna.
Balarama, and all of Krsna’s expansions–Vasudeva, Sankarsana, Pradyumna,
Aniruddha, Karanodakasayi Visnu, Garbhodakasayi Visnu, Ksirodakasayi
Visnu–all have the sentiment of being servants of Krsna.

apanake bhrtya kari’ krsne prabhu jane
krsnera kalara kala apanake mane

“[Balarama] considers Himself a servant and knows Krsna to be His master.
Thus He regards Himself as a fragment of His plenary portion.” (Cc Adi
5.137)

  And I have found this following info:
  
  It is Lord Balarama who expands into the great serpent known as Ananta, or Sheshanaga. He reposes on the Causal Ocean and serves as the couch upon whom Maha-Vishnu reclines. (Brahma-samhita 5.47). Ananta-Sesha is the devotee incarnation of God who knows nothing but service to Lord Krishna. With His thousands of mouths He always sings the endless glories of Lord Krishna. He also expands Himself to serve as Lord Krishna’s paraphernalia, including such items as the umbrella, slippers, bedding, pillow, garments, resting chair, residence, sacred gayatri thread, and His throne in the pastimes of Lord Krishna. Thus, He has attained and exhibits the ultimate end of servitude to Lord Krishna. (Caitanya-caritamrita, Madhya-lila, 5.120-124).
  
  So this info shows that the above info is some what correct. Yes Lord Balrama is the great serpent Sesha Naga on whom Lord Vishnu reclines but is also the expansion of the Supreme as mentioned in the SB.
  
  Could u pls kindly tell who is Lakshmana as well?
  
  Your servant
