My daya journée

Je veiniens d'Inde.

Je vais parler dues activités que j'ai faites hier.

Des = de+les. "Les" is the plural definite article
"Faites" agrees with "activités" because of a complicated rule called accord du COD antéposé. It's totally alright if you don't master it yet.

J'aie me suis réveille aé à huit heures.

Like all reflexive verbs, "se réveiller" needs "être" as an auxiliary verb
A = has ; à = at, to (preposition)

A ca époque, Je J'étais affamé.

"à cette époque" would mean in a different era or many years ago
You can use "à ce moment-là", but the best solution would be not to specify it
Je+vowel => j'

Alors, Jj'ai pris leu petit- déjeuner.

"j'ai eu" would strongly suggest it was given to you

jJ'ai mangeé deux oœufs et j'ai bu un verre due jus de l'orange.

J'aurais préféré que ce soit un/du parantha.

"un parantha" would mean the whole parantha bread, "du" would mean "some of it" (indefinite quantity of it)

Ces't ca, c'es't bon, ça.

The apostrophe hangs after the <c> because it replaces the falling the missing <e> that is dropped because of the following vowel
Ce+est => c'est

Apreès ca, Je suis(ça), j'ai été prêt aà travailler.

"je suis" would be the present tense
Pronouns are never capitalized when they don't start a sentence

J'ai pris mon ordinateur portable et j'ai commenceé à faire mon travail/travailler.

Commencer à/de faire qqch (there's a small difference in meaning implied by the two prepositions, but for now, you can consider they're equivalents)
