Hello Prit, and welcome to the forum! As for your questions:
1) May and June are excellent months if you're looking for fresh green scenery and (mountain) flowers. Weather circumstances can not be predicted at all. There have been years with great (summer) weather in May and there have been years with the exact opposite, so it's hard to say what next May will be like. At higher altitudes, you may still find (melting) snow resulting in mud, but if alpine hikes aren't your main goal, this shouldn't be a problem. Personally I would even prefer May over July or August, as it's more quiet and the scenery is beautiful, with still a bit more snow left on the mountain tops than in summer.
2) and 3) You've planned some very long trips from Lucerne. The trips to Engelberg and Zurich are relatively short, but especially those to Lugano, Zermatt and Lausanne require long travelling times. The timetable
will give exact travel schemes, helping you to find out how much time you'll be spending in the train. If you'd be doing all these trips, another disadvantage would be that you're not able to fully explore the beautiful surroundings of Lucerne, which has lots to offer. My advice would be to pick one or two bases and explore these regions, making only a few longer day trips. But you're right: that's only one opinion. If it's important to you to get a (quick) impression of many Swiss regions, and if you don't mind travelling a lot, your itinerary is fine. By the way, train travel in Switzerland generally is easy and relaxing, and offers great views along the way.
4) Yes, Grindelwald is situated at the foot of an impressive mountain range and offers wonderful views from the village. Although some might find it touristy, the location is great, and it won't be that crowded in May yet.
Does this answer some questions?
