cho irimi lolly (my name is lolly)

→ Jeo e ireum en lolly ipnida

(There are no subject particle 'en'. 'ipnida' is honorific speech which is put after noun.)

Hangul chua (i love the korean language)

→ Hangul eul joa hapnida

 (We need to put 'eul/rul' before object.)

cho dul dongsang (i have two brothers)

→ Jeonun donsang i dumyung isupnida.

Chinsha chua sesengnim (i really love being a teacher)

→ sunsaengnim i jincha daego sipsupnida.

tuwa juseyo hangul ...(please help me ?learn?)

→ Hangul garucheo juseyo.
