As you can see from this map, the Haifa "Mifratz" train and bus stations are on either side of a mall, so the distance is less than 150 m (sorry, but I have never been there so no personal experience):

The Leonardo Plaza is about a 10 minute walk from the Tiberias bus station (mostly downhill) so you may prefer to go on foot:

In any case, Uber does not operate in Israel. There will almost certainly be taxis waiting near the bus station. Insist that the driver turn on the meter (which he must do by law). You can also install the "GETT" app on your phone. You can use it to order taxis and to pay with credit card. Always ask for a receipt,
