Question

Write the plural command in Spanish that means 'write to me' and 'get up'.

Answer 1

the plural command in Spanish that means 'write to me' is escriban
the plural command in Spanish that means 'get up' Levántense (Uds.)

Answer 2

the plural I assume refers to the plural "you" , that is, you are giving the plural to two or more people.

first one, it would be the form for !write! in plural, which is:
Escriban
then you have to add the "me" :
escribanme

but you will need an accent now, since the number of syllables has changed, but not the syllable that is accented:
Escríbanme

for get up I will use: levantarse

it's a reflective verb, so it will be "se" instead of "me", but the rest will be as above:
Levántense.
