I dont know that you can brew green tea multiple times, I heard it gets very bitter. I drink black tea and often brew it 2-3 times.

Many people these days tend to use 'afternoon tea' and 'high tea' interchangeably as many mistakenly believe that there is no difference between the two, but there are. High tea is not the same as afternoon tea, and most of the time when people say 'high tea' they are actually referring to 'afternoon tea'. High tea was a working class family evening meal or supper served between 5-7pm. When tea became popular in Britain, workers would have to wait for tea time until after work. Instead of the finger sandwiches, scones and sweets that are usually served with afternoon tea, the high tea menu consisted of heartier dishes like meat, beans and potatoes. High tea was a nourishing meal after a long day of work usually served with a pot of strong black tea. The name high tea comes from the high dinning table and chairs where supper was eaten, which were quite different from the low, relaxing parlour chairs used for afternoon tea.

I think you might actually be referring to 'afternoon tea' and not 'high tea'. People often get the two mixed up, I explained the difference between the two in my answer to 'what is high tea?'. If you want to make high tea, simply make dinner and serve it with a strong pot of black tea. If you want to make 'afternoon tea', which people tend to mistakenly refer to as 'high tea', here is how you do it. All you need is black tea with little cakes and sandwiches, so if you want to make it at home you will need cake and sandwich like finger food. Scones with jam and cream are a really good idea too and very popular. You can add some fruits, chocolates, sweets - whatever you fancy, really! If you want it to be a little bit more special you can serve your pot of tea and little bits and pieces on a special high tea or cake stand along with some bubbles and enjoy with your friends and family. If you are willing to go the extra mile, add flowers for decoration. In terms of tea, I would suggest having a couple of different options like earl grey, lady grey or darjeeling.

This is a very important question, the secret to a great cuppa is infusion (brewing). Brewing really depends on the type of tea you have. The rule of thumb is that you use either hot or cold water and let it steep for the right amount of time in the right temperature. Time and temperature are key. Generally most black teas will require boiling hot water with a steep time ranging from 1-5min. Temperature and steeping time are very important for green teas. Depending on the tea variety it usually needs 70-95 degrees with a steeping time between 1-10min. We suggest to start with a short steep, taste it, and increase the steeping time by 30 seconds, until you like the taste. Herbal teas generally like boiling hot water and a longer steeping time. For iced tea depending on the tea type you either start with boiling hot water and let the beverage cool down, or you can steep in cold water.
