haha... most important question i guess is...
how heavy are u? =.=
if u are very heavy, then its definitely not enough!
if u r around 50kg, it may be ok.
8-9eggs, protein would be roughly 30g.
ur lunch and dinner, if u can get 70-80g then it will be just nice for ur 50kg.
but if u weigh much heavier, then haha... sorry to say, its not enough at all

we dont know how much u eat.
ur portion could be small or big, it varies.
so estimate around 20-30g for lunch and dinner.
total maybe 80-90g per day. close to 100g only

well, if u dont have money to even eat eggs, then bro... sorry, no one can really help u.
eggs are the cheapest source of protein.
if u want to get supplements like whey, its up to ur budget and ur need.
if u all also cant get, then slowly gain ur size la.
eat wat u can, and just let nature do its course.
no one can give u any help on this.
wat u need to repair ur muscles after workouts are proteins.
one piece of chicken? gosh... we do not eat chicken wing or drumsticks here for goodness sake.
u need protein, and get it from breastmeat pls... drumstick and wings? big no no... coz, they are lesser compared to breast meat.
breast meat probably 20-30g depending on size as well.
