Is it save to eat heated meal after 2 - 3 days(?)

Like the title said, I want to cook

1. Cajun chicken breast

2. Pasta and the bolognese sauce (separated)

3. Tortilla filling

Say I cooked all of those on sunday night, and after 2 hours I put all of them on the refrigerator (not freezer). On that morning I'll take those 3 meals to my office and put it on the office's refrigerator. The commute time is 1.5 hours btw (yeah I know it sucks).

Can I reheat those food using microwave at the office?

Say monday I eat the chicken breast, Tuesday I eat the pasta and Wednesday I eat the tortilla filling.

I've never done this before so please don't judge me.
