A quick look:

$HJUF is similar to a $VWRL. Not quite, but similar. The active fund has a little more information technology in it, which has probably resulted in better performance in recent years.
Fund: 1.45% management fee p.a.

$HJUI is similar to a DAX ETF (e.g. $LYY7 ). However, the fund has a focus on information technology. In comparison, the fund has performed worse over the last 17 years.
Fund: 1.45% management fee p.a.

$SR1J9K compares with the MSCI Stoxx 600 and according to their brochure the fund performs worse. The fund feels like a mixture of Stoxx600 and Momentum Europe.
Fund: 1.97% management fee p.a.

If the funds are from your father, it is possible that certain units were purchased before 2008. This means that they may even be tax-free to sell.

As @Epi and @Dividenden-Penner have written, you can proceed as follows. You need to form your own opinion and think about it. As a tip: also calculate the performance of a fund vs. an ETF over 30 years, including costs.
The 1.5% management fee is often a big factor over time...
