A seasonal trend would be a value that varies with the seasons of the year. An obvious one would be high and low temperatures; they are highest in summer and lowest in winter.
Seasonal trends are a subset of cyclical trends, which are values that vary and then return to the original value. For example, temperatures represent a daily cycle embedded within the seasonal cycle.
A random trend isn't really a trend at all. "Random" implies that there is no connection between measured values and the passage of time.
In a stock market, a secular trend refers to a long-term trend that consists of smaller bull and bear markets. For example, a secular bull market over the course of ten years would include a series of bull markets that were larger than bear markets coming in between them.
