Answer:
Well, first of all, I should point out that every sentence has capitalization errors. That's a 'writing mechanics' problem though, not a grammatical problem.
The true grammatical errors are....
1.) Â fragment
2.) Â run-on AND tense issues
4.) Â Did you really mean to type 'her,' or did you mean to type 'here'? It doesn't make any difference really since neither sentence version makes sense.
Numbers 3 and 5 are grammatically correct.
