Is it ok to have my baby's bath twice, morning and evening?  

As long as she isn't chilled, there shouldn't be a problem. Be careful that her skin doesn't get dried out also. Too many lotions would do more harm than good. Maybe one bath and one lite sponge bath.

This seems really excessive to me. I bathe my daughter only every few days unless she is dirty. A drawback from two baths a day is that your baby may get really dry skin. If you notice this happening then I would stop doing it so frequently. Otherwise, there isnt really any harm in it.

In a tropical climate, she should probably be wiped off a couple of times a day, because of the sweat & ickiness. I know I feel cooler when I'm clean. In dry weather (or cold), you need to make sure the skin is moisturized afterwards. I don't know how that works there. She might need a powder or something applied more often. Listen to your doctor. If they say it's ok, it probably is.

I had several pediatricians tell me that bathing my abby everyday would dry their delicate skin out too much and that most ababies only needed a bath every other day UNLESS they made a mess in their diaper taht went elsewhere. They also said just to wash their bottoms everyday, of course that makes sense. I never used much lotions on my kids as they were sensitive to some of them, so the not drying the skin made sense too.
