@Jean700 How nice of you to think of this. People in these types of jobs in Mexico usually earn shockingly low wages and will be very appreciative of a tip. The Mexican minimum daily wage is something like about 90 pesos, the equivalent of about $4.50US, although many people get paid more than that, especially in heavily touristy areas. For instance, where I live, maids are up to about 100 pesos/hr. ($5) now. Which is still peanuts to most of us.
I honestly don't know exactly how much to recommend-one of the problems I've found living in Mexico is that some foreigners tend to tip so much that the locals come to expect it, and then start giving you dirty looks if you can't afford to tip that much. Also, tipping a security guard some grand amount might lead them to think you are loaded and maybe your stuff won't be so safe.
Off the top of my head I'd say if you tipped each security guard 100-150 pesos, they'd be appreciative. I'd tip the maid 50 pesos/day. But if it's a really fancy, high end place, they could be accustomed to getting larger tips.
Maybe some other Mexican hosts will chime in here. And you could also ask your host what they feel is an appropriate tip for their staff.
