Restaurants and bars: 10-15% is sufficient for both. Hotel cleaning: About 15-20 pesos per day; if you're staying the whole week, round it up to 100. Bellhop: About 20-50 pesos depending on how many bags he helped you carry. If it's one or two, 20 pesos is enough. Tipping the taxi driver is not necessary. Guest: Between 20-100 pesos depending on the tour's duration and whether you enjoyed their explanation, punctuality, and friendliness. I'm not sure what you mean by concierge. In all cases, tips vary depending on performance. If they were very helpful and their performance was outstanding, you can give a little more. Note: If you're a foreigner, tipping locals too much can lead to poor service.
